The NACA Oil-Damped V-G Recorder

Abstract

An NACA oil-damped V-G recorder has been developed in which viscous damping of the accelerometer results in improved frequency response, reduces susceptibility to vibration, and eliminates the necessity for field adjustments of damping. The airspeed element has been temperature- compensated and approximately linearized. The new V-G recorder and its performance characteristics are described and the results of tests, which demonstrate the improvements over the older design in which the accelerometer unit was friction-damped, are presented.
